METHOD FOR PRODUCING HIGH-SPEED VERTICAL NPN BIPOLAR TRANSISTORS AND COMPLEMENTARY MOS TRANSISTORS ON A CHIP

摘要

The invention relates to a method for producing high-speed vertical npn bipolar transistors and complementary MOS transistors on a chip. In order to produce these high-speed vertical npn bipolar transistors and complementary MOS transistors on a chip, all technological method steps for producing the vertical structure of the collector, base and emitter in the active region of the npn bipolar transistors as well as for laterally structuring the collector regions, base regions and emitter regions are performed before the troughs and the gate insulating layer for the MOS transistors are produced.
